Study Notes
Nonequivalent Groups Design
- Characterized by the absence of random assignment of subjects, which can lead to bias.
- This design often involves groups that were formed based on preexisting characteristics rather than random selection.
Threats to Validity
- Individual differences pose a significant threat to the validity of nonequivalent group designs, as variations among participants can influence outcomes.
Differential Research Design
- Refers to a type of research study that compares preexisting groups, typically without the manipulation of variables.
Post Test-Only Nonequivalent Control Group Design
- Also known as the static group comparison, this design involves measuring outcomes only after the treatment has been administered, without any pre-intervention assessments.
Pretest-Posttest Nonequivalent Control Group Design
- This design features both pre- and post-intervention measurements for the control and experimental groups, allowing for a comparison of changes over time.
